Company spokesman Todd Martin says the jobs will be cut at the Susquehanna Power Plant in Salem Township, near Berwick. That's about 80 miles northeast of Harrisburg.
Another seven workers who support the plant but are based in Allentown are being cut, too. The plant has about 1,100 workers.
The cuts also include 29 workers at Talen's Montour Steam Electric Station near Washingtonville, and 42 jobs at its Brunner Island plant in York County.
The International Brotherhood of Electrical Workers Local 1600 was notified of the cuts on Tuesday and has 10 days to review whether the cuts are in accordance with workers' seniority.
